Treatment Recommendations

Warm stones using a safe, professional method such as a roaster-style warmer, Theratools Warming Tray, or Mobile Warming Bag. Always test the stone on your forearm first—it should feel comfortably warm, never hot. Then, check in with your client before placement to ensure it feels safe and soothing. Use for slow, fluid strokes across large muscle areas to help soften tension, promote circulation, and offer a grounding, restorative experience. Ideal for sports recovery, contrast therapy, and deep relaxation rituals.
